STAPLE-SETTING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 790,773, dated May 23, 1905.

Application filed November 14,1904. Serial No. 232,633.

To all whom, it flea-y concern:

Be it known that I, FRANK WIsEMAN, residing at John Day, in the county of Grant and State of Oregon, have invented a new and useful Improvement in Staple-Setting Implements, of which the following is a specification.

This invention relates to certain improvements in staple-setting implements, and has for its object to provide an implement of this character of a simple and effective construction and which is more particularly adapted for use for stapling seams of boots and shoes and for uniting pieces of leather or other fabrics; and the present invention particularly seeks to provide an implement of this character which is an improvement on the implement disclosed in my copending application, filed May 27, 1904, Serial No. 210,121.

In its generic nature the invention consists in a pair of nipper or tongue-like jaws, the lower one of which carries an adjustable anvil, while the upper jaw carries a staple hold ing and setting head of such construction as to be readily set to different positions with respect to the vertical .aXis of the head, and the said anvil being so constructed as to be capable of being set in the different positions to correspond with those of the staple-holder.

With other objects in view, which will hereinafter be apparent, the invention consists in certain novel details of construction, arrangement, and combination of parts, all of which will be first described in detail and then specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of my invention as applied for use. Fig. 2 is a side elevation thereof, the upper jaw carrying the reversible head being shown in vertical longireference indicate like parts in all of the figures,'1 1 designate the jaws of the implement A, which jaws are pivoted together, as at 1 and are formed with the usual handle members 1 1, as clearly shown in Fig. 1. To the lowef jaw 1 and at the end thereof I form an anvil holding portion 2, having a vertical bore 2 and V-shaped notches 2 to receive the anvil 3, which anvil 3 also includes a shank 3, which projects through the bore 2 and engages with the flat spring member 3 secured to the under side of the lower jaw 1. The anvil 8 also has a V-shaped portion for engaging with the V-shaped notches 2 of the anvil-holding portion 2 when the said anvil is in its various adjusted positions. In the practical application of my invention the anvil 3 can be moved in the arc of' the circle having its center in the axial line of the plunger 5 when-the jaws are closed.

The upperjaw 1 is provided with a bearing member a, having its front face curved and of semicircular shape in cross-section, and where the bearing member a and the jaw members 1 join the said jaw is formed with shoulders a a for the purposes to appear. The bearing member a is of a less length than the vertical length of the front face of the jaw 1, whereby to leave a cut-away portion 6 to receive a locking-head C, having peripheral grooves 0 and a T-shaped portion 0 to cooperate with the T-shaped groove cl of the staple-holder D, hereinafter referred to. The head C also has a square aperture 0 to receive a square end 5 of the stem 5 of the plunger 5, which stem passes through a vertical longitudinal circular bore a in the bearing member a. 5 designates aT-shaped portion on the head of the plunger 5, which also cooperates with the groove cl of the holder D. This holder D (shown in detail in Fig. 10) consists of a longitudinal member having a T-shaped groove (Z running its entire length,-

and the said member D is also provided at its upper edge with a lug 0?, adapted to enter and cooperate with the recesses 0' in the head portion 6 of the presser member E, attached to the upper face 1 of the upper jaw 1 by the screws in or otherwise, and the upper face 1 of the jaw is flat to form a bearing portion for the presser member E. The head 0 of the presser member E also carries a key 6 adapted to enter the grooves 0 in the head C, and a corresponding groove 1 in the jaw 1 to lock the head 0 and prevent its turning, the lug 0Z engaging the recess 6' in the like manner and also serving to hold the plunger and staple-holder in their adjusted positions. The presser member IE, it should be understood, is formed of spring metal, whereby to serve to maintain the staple-holder D with its upper edge flush with the flat upper face of the jaw 1", and the said presser member lies against the said fiat upper face of the said jaw 1*. To further limit the vertical motion of the staple-holder D, I provide the same with a stop d between the T-shaped portion of the head C and the plunger 5. So far as described it will be seen that by constructing the stapleholder and plunger member in the manner shown and described the same may be turned with the staple-holder in front or at either side of the implement to permit of its operation without turning the piece to be worked upon. When the head is turned with the staple-holder at either side of the implement, the said staple-holder will engage the shoulders a a and be steadied thereby.

In the practical operation of the invention the operator places the staple in the stapleholder below the plunger and then places the article to be worked upon over the end of the lower jaw, as shown in Fig. 1, and brings the handle members together, the stapleholder first coming into contact with the goods to be worked upon, and then the plunger as the jaws are brought closer together will force the staple through the article to be worked upon with the points of the staple into engagement with the anvil and clench the same. At the same time the staple-holder will remain stationary and cause the presser member to rise with its key out of engagement with the grooves of the head 0 and the groove in the upper jaw, and thereby unlock the head and the jaw. The head and plunger, together with the staple-holder, will, however, be prevented from turning at this time by the lug on the upper edge of the stapleholder being held within the recess of the presser-member head. Now if it is desired to put a staple into the goods at right angles to the one just placed it is only necessary to raise the presser member out of engagement with the head and the staple-holder, when the head, together with the staple-holder, may be rotated to either side of the instrument, as shown in dotted lines in Fig- 3.

The anvil 8 is turned to either side of the holder to cooperate with the holder and the presser member when it is turned to either side of the implement, it being only-necessary to disengage the V-shaped-tooth 3 of the anvil from the V-shaped notch 2 of the anvil-holding portion of the jaw, when it may be turned to the desired position. As soon as the operator releases the anvil the spring 3 forces the anvil member 3,with its V-shaped tooth, into engagement with the V-shaped notch of the jaw and securely holds it in such position.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the advantages and complete operation of my invention will be readily understood by those skilled in the art to which it appertains.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A staple-setting implement comprising a pair of jaws, the upper jaw having a bearing portion, a plunger revolubly adjustable and having a spindle projecting through said bearing portion, a locking-head on the projecting portion of said spindle, said plunger also including a staple-engaging portion, a stapleholder carried by said locking-head and staple-engaging portion, and having vertical movement thereon, means for limiting such vertical movement, and means for locking said locking-head to its adjusted positions, said lower jaw having an aperture and a plurality of V-shaped grooves, an anvil including an elongated body portion having a V-shaped portion for engaging the V-shaped grooves of the lower jaw and a shank for passing through the aperture of the lower jaw, a spring secured to the lower jaw and to the anvil-shank for holding the anvil in engagement with the V-shaped grooves for the purposes specified.
